正則表達式匹配兩個字符串之間多次出現的字符串

Question

我正在嘗試匹配兩個字符串之間多次出現的數字。

"ELE:和":{"isHidden":true}獲取之間的數字。

我有(?<={"ELE:)(.*)(?=":{"isHidden":true})但這會選擇整個組。

我如何使它只匹配數字？

{"version":2,"(sectionConfig)":{"SECT:1236":{"children":{"ELE:1826":{"children":{"ELE:4217":{"(isHidden)":true},"ELE:22043":{"isHidden":true},"ELE:4253":{"isHidden":true},"ELE:1796":{"isHidden":true},"ELE:3907":{"isHidden":true}},"defaultSelectionId":"ELE:1781"},"ELE:1850":{"defaultSelectionId":"ELE:2657"},"ELE:1832":{"children":{"ELE:602":{"isHidden":true},"ELE:3864":{"isHidden":true},"ELE:650":{"isHidden":true}},"defaultSelectionId":"ELE:605"},"ELE:3711":{"isHidden":true}}},"SECT:2789":{"children":{"ELE:3923":{"isHidden":true},"ELE:3932":{"isHidden":true},"ELE:3920":{"isHidden":true},"ELE:3929":{"isHidden":true},"ELE:3938":{"isHidden":true},"ELE:3917":{"isHidden":true},"ELE:3926":{"isHidden":true},"ELE:3935":{"isHidden":true},"ELE:2834":{"isHidden":true},"ELE:2837":{"isHidden":true},"ELE:2960":{"isHidden":true},"ELE:2675":{"isHidden":true},"ELE:2933":{"isHidden":true},"ELE:2690":{"isHidden":true},"ELE:2717":{"isHidden":true},"ELE:3011":{"isHidden":true},"ELE:2681":{"isHidden":true},"ELE:2723":{"isHidden":true},"ELE:2693":{"isHidden":true},"ELE:2795":{"isHidden":true},"ELE:3014":{"isHidden":true},"ELE:2708":{"isHidden":true},"ELE:2975":{"isHidden":true},"ELE:2729":{"isHidden":true},"ELE:2996":{"isHidden":true},"ELE:2987":{"isHidden":true},"ELE:2672":{"isHidden":true},"ELE:2684":{"isHidden":true},"ELE:2669":{"isHidden":true}}},"SECT:2531":{"children":{"ELE:1862":{"children":{"ELE:26661":{"isHidden":true},"ELE:26682":{"isHidden":true},"ELE:26631":{"isHidden":true},"ELE:26601":{"isHidden":true}},"defaultSelectionId":"ELE:647"},"ELE:2690":{"isHidden":true},"ELE:2637":{"isHidden":true},"ELE:2485":{"isHidden":true},"ELE:1832":{"children":{"ELE:650":{"isHidden":true},"ELE:602":{"isHidden":true}},"defaultSelectionId":"ELE:605"},"ELE:2599":{"isHidden":true},"ELE:2521":{"isHidden":true},"ELE:1826":{"children":{"ELE:27478":{"isHidden":true},"ELE:27469":{"isHidden":true},"ELE:27460":{"isHidden":true},"ELE:27445":{"isHidden":true},"ELE:27436":{"isHidden":true},"ELE:27427":{"isHidden":true},"ELE:1796":{"isHidden":true},"ELE:4217":{"isHidden":true},"ELE:22043":{"isHidden":true},"ELE:27115":{"isHidden":true},"ELE:3907":{"isHidden":true}},"defaultSelectionId":"ELE:1781"}}}}}

Answer 1

您可以使用

(?<="ELE:)\d+(?=":{"isHidden":true})

請參閱正則表達式演示。

細節

• (?<="ELE:) - "ELE:必須立即出現在當前位置的左側
• \d+ - 一位或多位數字
• (?=":{"isHidden":true}) - ":{"isHidden":true}必須立即出現在當前位置的右側。
